Prosthesis with microprocessors is controlled by app

Instead of having to change her prosthesis every time she engages in a different activity, Tara Butcher now wears the new Magellan leg, which recently became available in the U.S. Sensors in the foot enable microprocessors in the ankle to adapt to different types of terrain, and Butcher can make adjustments using an application on her smartphone. The app also shares information electronically with Butcher’s prosthetist.
